If the JATHO/JATTO family settled in the Hecker area of Monroe Co., Hecker did not become part of Monroe Co. until quite a while after the county. was organized. I can't remember the exact year There are still JATHOs in Monroe Co. You may want to write to them direct for family information. At this time, no member of MCGS is researching the JATHO surname. However, a member is researching ACKER and I believe there is a kinship there. If you would like her address, let me know. Janet Flynn, Secretary M.C.G.S.
